Improved electrical performance of PDMS and PEDOT: PSS composites with MWCNT and AgNP particles.

ABSTRACT: The fabrication of conductive polymer composites (CPCs) using polydimethylsiloxane (PDMS) and poly(3,4-ethylene dioxythiophene): poly(4-styrene-sulfonate) (PEDOT: PSS) as a matrix with multi-walled carbon nanotubes (MWCNTs) and silver nanoparticles (AgNPs) as fillers was investigated to determine their potential for use in applications such as electromagnetic interference (EMI) shielding, sensors, and thermal switches/cut-offs. The effect of the fillers was investigated using MWCNTs of different sizes and including both MWCNTs and AgNPs at different ratios. Scanning electron microscopy (SEM) analyzed the morphology of the CPCs showed that the inclusion of AgNPs in the PDMS matrix resulted in a particle size gradient, with larger particles at the bottom of the CPC, although SEM confirmed th
